Problems solved by technology

[0002] At present, many universities, scientific research institutions and enterprises often involve universal testing machines, fatigue testing machines, bending and torsion testing machines, etc. in the process of material performance testing and testing. The testing machines themselves are very expensive and the maintenance costs are relatively high. At the same time, the precision requirements of the testing machine are also high, and the equipment will inevitably generate more heat during operation, and for most materials, the temperature will be too high to cause thermal expansion, and for the testing machine, it will affect its test accuracy, etc. , which often requires cooling treatment to ensure the constant oil pressure of the testing machine and the stability of the performance of the equipment. It is also necessary to prevent the premature aging of the lubrication and hydraulic oil caused by excessive temperature, thereby reducing the service life of the lubricating oil and hydraulic oil.
However, if the cooling gradient is too large or too small during the cooling process, it is not conducive to the safe and stable operation of the equipment.
If the cooling gradient is too small, the actual cooling effect will not be achieved. If the temperature is too high, the oil pressure in the equipment will be unstable, which will affect the stability of equipment operation and the accuracy of the test; otherwise, the cooling gradient will be too large, and long-term operation will also cause energy loss. and waste of water resources
At present, all units generally use tap water to directly cool down, which increases the error of the test and also reduces the service life of equipment and oil, and also wastes a lot of water resources, which is very unfavorable to the energy-saving concept of enterprises.
[0003] In terms of equipment installation space, many units use independent tap water single circulation to directly cool down, which is acceptable for short-term operation of a single equipment, but there is obviously a huge waste of resources (installation space, tap water and circulation equipment materials) for multiple equipment , especially for multiple devices running at the same time, the waste is particularly obvious
